QPEGIFICATION forming part of Letters Patent No. 621,598, dated March 2 1, 189 9.

Application filed February 10, 1898. Serial No- 669,865. (No model.) 4

To all whom it may concern: Be it known that I, JOHN G. BODENSTEIN, a citizen of the United States, residing at Staatsburg, Dutchess county,NewYork, have invented certain new and useful Improve ments in Ice Plows or Markers, of which the following is a specification. 1

This invention relates to improvements in ice-plows, the improvements being applicable not only to ice-plows, properly'so called,

but also to markers, which are similarto plows in construction and operation, but are of lighter build.

My invention comprises an improved mode of attachment of the swing-guide.

- In the accompanying drawings, which form a part of this specification, Figure 1 is a plan View of an ice-plow provided with my improvement. Fig. 2 is a sectional detail end view of the front portion thereof. Fig. 3 is a transverse section showing the swing-guideattaching device.

Mounted in the frame A in the usual manner are tooth-supporting plates E, upon which rest the insertible teeth 0, said teeth being curved, as shown, and being inserted endwise between'the successive plates E and between the side bars a a of frame A.

G represents the swing guide-plate, connected to the main frame A by arms or rods g g, each of which engages with said main frame by a lock or catch consisting of T or L shaped ends or side extensions 9 on said arms engaging in slots formed in brackets 11 on the frame A, said side extensions being in the general plane of the guide-frame G g g. Each of said brackets has a circular bore or channel 10, adapted to receive the flat cross-pieces 9 on arms 0 and permit same to turn freely therein. At the top of this bore or channel 10 is a longitudinal slot 13, which is comparatively narrow, so that the flat crosspiece 9 cannot pass flatwise through this slot, but can pass edgewise through same. Acrosschannel 12 is also formed in the bracket to receive the arm g or g as the latter swings down on one side or the other. The ,longitudinal slot 13 in the front bracket is preferably inclined at a slight angle from a longitudinal line, so that when the swing guideframe is in a central or vertical position the T or L arms cannot be detached from the slots by a simple upward movement, such as might accidentally take place in shifting the said frame from one side to the other from the rear of the plow or marker. To detach the swing guide-frame from the main frame of the plow, the said guide-frame is first raised to a vertical-position. Then the rear T or L arm, which lies in under the longitudinally-extending slot 13, can be raised through said slot, and the guide-frame may be turned horizontally to bring the other T or L arm into alinement with the overlying slot, whereupon it may be passed through same, and the whole guide-frame thus removed from the plow. The main object of such removal is to enable the substitution of a different size of guide, and as this often has to be done while the plow is coated with ice the advantage of a readily-detachable construction such as above described is evident.

g is the usual swing-rod, whichis connected to the swing guide-frame by an eye-joint and at its rear end is connected to the plow-handle frame in the usual manner, this being no part of my invention.

q is a diagonal brace-rod for the swing guide-frame.

The slots 13 being at the top of and contrally located over the channels 10 and the side extensions 9 being in the general plane of the guide-frame G g g, it is apparent that the said frame can only be removed when it is raised to a vertical position and is locked when down on either side.

When the swing-guide is down on either side, the locking devices above described interlock with one another to prevent any disengagement of the guide-frame by jarring.

The brackets 11 being rigidly attached to the main frame of the plow form substantially portions thereof, and it is evident that the necessary slots 10, 12, and 13 could be formed directly in the plow-frame, if desired.

Having thus described my invention, the following is what I claim as'new therein and desire to secure by Letters Patent:

1 1. In an ice-plow, the combination with the main frame thereof, having portions formed with longitudinal channels, and slots located extensions located in the general plane of the guide-frame engaging in said channels and capable of passing edgewise but not flatwise through said slots so as to free the guideframe when it is in a vertical position but to lock it when down on either side.

2. In an iceplow, the combination with the main frame thereof, having portions formed with longitudinal channels and with slots 10 above said channels, of a swing guide-frame having bars with side extensions engaging in said slots and channels, one of said slots being angularly placed so as to prevent disengagement of the swing guide-bar therefrom until the guide-frame is turned at an angle.
